[0001] The invention relates to the technical field of molding equipment, and in particular to a high-elastic material molding device for a water pump seal. Background Art

[0002] Water pumps are widely used in many industrial and civil fields, and water pump seals play a vital role in ensuring the normal operation of water pumps and preventing liquid leakage. With the continuous improvement of water pump performance requirements, higher requirements are also placed on the performance of seals. For example, high elastic materials need to be used to better adapt to various working conditions in water pump operation and achieve good sealing effects.
